Glen Jenkins was a new character, debuting in the second season of Siren.
He was a drug-dealer, earning him the name "the Chemist" who had sold illegal drugs to the late Donnie Price and even Susan Bishop.
He had met and befriended the conflicted, alcoholic Susan Bishop and seems to have gone out with her a few times. He is killed by Ryn when she tries to protect Maddie from his attacks by having his neck snapped. When Dale arrives, he moves Glen's corpse is to the bathtub and then injures it to make sure that it looked like an accident and not a murder.
- It was he who had convinced Susan to return to Bristol Cove, and that he has been her drug supplier for quite some time.
- After Ryn snapped his neck, Dale investigated the motel room he stayed in. He finds numerous quantities of cocaine and other forms of narcotics, Marissa to notified him about Glen's alias known as "The Chemist". From this point onward, the drug crisis in Bristol Cove would then be resolved offscreen.
